[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a load-bearing wall structure that can be efficiently formed.
[0002]
[Background Art and Problems to be Solved by the Invention]
In the wall construction method such as the panel construction method and the two-by-four construction method, when forming a load-bearing wall on the upper floor above the opening, horizontal members such as small walls and lintels are placed between the wall assemblies installed at intervals. It is attached to form an opening, on which the upper floor and wall set are installed. Then, the upper floor and the wall assembly are fastened with a torsion bolt or the like, and the small wall or the like is connected to the upper floor by a gusset plywood or the like.
[0003]
However, in the conventional structure described above, it is always necessary to separately perform the fixing work of the wall group and the attaching work and connecting work of the small wall or the like at the construction site. For this reason, it takes time for construction work, and it is difficult to meet the demand for work efficiency improvement.
[0004]
This invention is made | formed in view of the said subject, The objective is to provide the bearing wall structure which can form an opening part and a bearing wall of the upper part more efficiently.
[0005]
In addition, in search of a technique for solving the above problems, the present applicant conducted a search using a prior art search (PATOLIS) of the Japan Patent Information Organization (JAPIO). Sho-58-181812 was extracted. However, the technique disclosed in the publication is for integrally attaching and fixing the opening panel frame and the waist wall to the structural housing at the same time, and thus the above-described problem cannot be solved.
[0006]
[Means for Solving the Problems]
In order to solve the above-mentioned problem, the present invention has a wall assembly in which a face member is attached to a frame body in which a longitudinal member and a transverse member are assembled into a rectangle, and is arranged above the opening via a floor, It is a load-bearing wall structure that is fastened to a horizontal member that forms an upper portion of the floor and the opening by a hardware screwed into the bolt,
The bolt is attached by vertically penetrating the cross member and the floor body,
The horizontal member is made of a wooden material, and has at least an upper surface with a hole into which the hardware can be fitted,
The hardware has a bottomed cylindrical shape, has a thread groove to be screwed to the bolt on the inner surface, and has a plurality of annular protrusions on the outer surface to prevent the horizontal member from coming off. The open end is fitted into the hole with the upper end upward, the outer diameter of the open end is smaller than the outer diameter of the other part , and a gap is secured on the outer periphery of the end, and It is fixed to the horizontal member with an adhesive .
[0007]
According to the present invention, the horizontal member and the upper floor that form the upper portion of the opening can be formed by simply screwing together the bolt that penetrates the horizontal member and the floor of the wall set up and down, and the hardware embedded in the horizontal member. It is possible to easily tie the floor body and the wall set thereon. That is, the opening and the bearing wall above it can be efficiently formed with a small number of operations.
[0008]
The specific structures of the bolts and hardware are not particularly limited as long as they can be screwed together to securely join the horizontal member and the floor and wall assembly on the upper floor.
[0009]
The horizontal members include all horizontal members that form the upper part of the opening, such as lintels and small wall panels.
[0010]
[0011]
Furthermore , since there are convex portions on the outer surface of the hardware, the convex portions are scratched and are difficult to come off from the horizontal member. In particular, since the horizontal member is made of a wooden material having elasticity, it is possible to further prevent the hardware from coming out of the horizontal member by forming the hole slightly smaller than the outer diameter of the hardware. Therefore, it is possible to obtain a load-bearing wall structure that can maintain a secure tight state.
[0012]
Since the hardware has a bottom, it is difficult for wood chips or the like that hinder screwing to enter the hardware.
[0013]
Further, the large can of the convex portion, when reference is made to the number, as long as possible achieve the above object, not particularly limited.
[0014]
[0015]
[0016]
[0017]
[0018]
Further , since the hardware is fixed by the adhesive, the hardware is difficult to come off from the horizontal member. In addition, since the outer diameter of the open end is smaller than the outer diameter of the other part, a gap is created between the hole and the outer diameter of the end, and excess adhesive is collected in this gap for bonding. It is possible to prevent the agent from entering the hardware from the end. Accordingly, it is possible to easily attach the hardware to the horizontal member.

DETAILED DESCRIPTION OF THE INVENTION
Next, embodiments of the present invention will be described in detail with reference to the drawings.
[0023]
FIG. 1 is a longitudinal sectional view of a physical strength wall structure which is not included in the present invention but is shown as a reference . In the figure, only the upper part of the opening is drawn as a cross section.
[0024]
In the figure, a floor 20 that forms an upper floor is placed on a horizontal member 30 that forms the upper part of the opening 100, and a wall that forms a load bearing wall on the upper floor is placed on the floor 20. Set 10 is installed. The wall assembly 10, the floor body 20, and the horizontal member 30 are fastened by bolts 40 and hardware 50.
[0025]
More specifically, the wall set 10 is formed by sticking the face material 16 to both surfaces of a frame 15 in which the vertical members 12 and the horizontal members 14 are assembled in a rectangular shape. By this face material 16, a desired proof stress is imparted to the wall set 10. The wall set 18 forming the side end of the opening 100 also has the same configuration as the wall set 10.
[0026]
The floor body 20 is formed by attaching a face material 24 to the upper surface of a frame body in which frame materials are assembled into a rectangle.
[0027]
In this embodiment, these wall sets 10 and 18 and the floor body 20 are all made of a woody material.
[0028]
The horizontal member 30 is a lintel and is made of a wooden square. A hole 32 for attaching the metal object 50 is formed on the upper surface 30 a of the horizontal member 30. The hole 32 is formed to have a diameter slightly smaller than the outer diameter of the metal object 50 and at least a depth that prevents the metal object 50 from protruding from the upper surface 30a.
[0029]
It is also possible to form the hole 32 so as to penetrate from the upper surface 30 a to the lower surface 30 b of the horizontal member 30. Further, as the horizontal member 30, a small wall panel in which a face material is attached to a rectangular frame can be used.
[0030]
The bolt 40 is a torsional bolt having a screw thread at both ends, and an upper end portion is fixed to the horizontal member 14 with a washer 42 and a nut 44, and a lower end portion is fixed to the horizontal member 30 via a hardware 50. Further, the bolt 40 has sufficient strength to bind the wall set 10 to form a bearing wall, and penetrates the horizontal member 14 and the floor body 20 on the lower side of the wall set 10, and the hardware in the horizontal member 30. It is formed to have a length that can be screwed to 50.
[0031]
For the washer 42 and the nut 44, those having a known configuration are used. Therefore, detailed description thereof will be omitted here.
[0032]
Instead of the bolt 40 and the nut 44, a bolt having a head portion and a shaft portion having a predetermined length may be used.
[0033]
The metal object 50 has a bottomed cylindrical shape, includes a thread groove 52 on the inner surface, and includes a convex portion 54 on the outer surface. Then, the hardware 50 is fitted into the hole 32 of the horizontal member 30 with the bottom facing downward.
[0034]
Here, a longitudinal sectional view of the metal object 50 is shown in FIG. 2A, and a plan view is shown in FIG. In these drawings, the inner side of the metal object 50 has a hexagonal cross-sectional shape at the open end portion 50a and a circular shape at the intermediate portion 50b and the lower end portion 50c. Further, as shown in FIGS. 1 and 2A, the screw groove 52 that is screwed into the bolt 40 is formed in the lower end portion 50 c of the metal object 50. The inner diameter of the intermediate portion 50b and the opened end portion 50a is formed larger than the diameter of the bolt 40.
[0035]
The inner diameter of the intermediate portion 50b can be matched with the inner diameter of the lower end portion 50c, and the thread groove 52 can be formed on the entire inner surface. Moreover, it is also possible to make the inside of the open end 50a into a polygonal shape other than a hexagon or a circular cross-sectional shape.
[0036]
The convex portion 54 of the metal object 50 is formed in a thread shape in order to prevent the metal member 50 from coming off from the horizontal member 30 and to facilitate embedding in the horizontal member 30. The size and pitch of the convex portions 54 are set in consideration of the ease and speed of construction work, the required friction strength, and the like.
[0037]
The overall size of the hardware 50 is determined in consideration of the size of the bolt 40 to be used, the size of the horizontal member 30, the friction strength to be realized, and the like.
[0038]
The hardware 50 having such a configuration is embedded in the horizontal member 30 by a method as shown in FIG. That is, as shown in the figure, the lower end portion of the high nut 60 having a size that fits the cross-sectional shape inside the end portion 50a is fitted into the end portion 50a of the hardware 50, and the wrench 62 is attached to the upper end portion of the high nut 60. The metal object 50 is rotated about the axis center through the attachment and the wrench 62. As a result, the hardware 50 moves up and down along the thread-like convex portion 54. Therefore, if the wrench 62 is moved in a direction in which the hardware 50 moves downward, the hardware 50 is easily embedded in the horizontal member 30. The mounting work of the hardware 50 is completed in advance at a low place in a factory or a construction site.
[0039]
What is necessary is just to rotate in the reverse direction by the same method, when removing the metal object 50. FIG. Further, instead of using the high nut 60 and the wrench 62, a spanner having an end that can be fitted to the end 50a may be used.
[0040]
FIG. 3 is a side view showing a method for attaching the hardware 50.
[0041]
By having such a configuration, the following operational effects are produced.
[0042]
First, by connecting the bolts 42 and the hardware 50, the upper floor wall set 10, the upper floor 20, and the horizontal member 30 below can be fastened together. Here, since the bolt 42 and the metal object 50 can be screwed together, they can be easily connected by simply rotating the bolt 42. Further, since the inner diameter of the metal piece 50 is larger than the lower end portion 50c having the thread groove 52 at the end portion 50a and the intermediate portion 50b, the end portion of the bolt 42 and the thread groove 52 can be quickly screwed together. And since the convex part of the outer surface of the metal object 50 makes a screw thread shape, it can be easily attached to the horizontal member 30 only by rotating the metal object 50 around the axis center. Further, since the inside of the end portion 50a has a polygonal cross-sectional shape, such a rotation operation is facilitated. Thus, since each operation is simple and the number of steps is reduced, it is possible to efficiently form the opening and the bearing wall on the upper floor located above the opening.
[0043]
Further, since the screw groove 52 inside the hardware 50 is formed only at the lower end portion 50c of the hardware 50, any bolt can be screwed as long as it has a threadable thickness and length. . Therefore, the common use of the bolts 40 used in other parts of the building and the bolts 40 can be achieved. Therefore, the cost can be reduced. In addition, in order to fix the horizontal member 30 more reliably, it is preferable to join the horizontal member 30 and the wall set 18 adjacent thereto with a nail or the like or attach a vertical frame.
[0044]
FIG. 4 is a longitudinal sectional view showing a main part of an embodiment of the load bearing wall structure according to the present invention .
[0045]
In the figure, a hole 82 of a predetermined size is formed in the upper surface 80 a of the horizontal member 80, and a metal object 70 is inserted into the hole 32 and fixed with an adhesive 76. Further, the hardware 70 is attached so as not to protrude from the upper surface 80 a of the horizontal member 80.
[0046]
Here, the metal object 70 has a bottomed cylindrical shape, and the outer diameter of the opened end portion 70a is smaller than the outer diameter of other portions. Accordingly, when the end portion 70a is attached to the hole 82 with the end portion 70a facing upward, a gap is secured around the end portion 70a. For this reason, excess adhesive 76 can be accumulated in the gap to prevent the metal 70 from entering the metal 70, and the metal 70 can be easily bonded.
[0047]
On the outer surface of the metal object 70, a plurality of annular convex portions 72 centering on the axis center are formed. As a result, a sufficient amount of the adhesive 76 can be accumulated between the hole 82 and the metal piece 70, and it is easy to realize reliable bonding and fixing.
[0048]
In addition, a screw groove (not shown) is formed on the inner surface of the metal object 70, and can be screwed with the bolt 40 shown in FIG. This thread groove may be formed on a part of the inner surface as in the above-described hardware 50 or may be formed on the entire inner surface.
[0049]
By using the hardware 70 having such a configuration instead of the hardware 50 shown in FIG. 1, the opening and the load bearing wall on the upper floor located above the opening can be efficiently formed.

【The invention's effect】
As described above, according to the present invention, the upper part of the opening is formed only by screwing the bolts passing vertically through the horizontal member and the floor of the wall set and the hardware embedded in the horizontal member. It is possible to easily tie the horizontal member to the upper floor and the wall set thereon. That is, the opening and the bearing wall above it can be efficiently formed with a small number of operations.
[0061]
Moreover , since there are convex portions on the outer surface of the hardware, the convex portions are scratched and are difficult to come off from the horizontal member. In particular, since the horizontal member is made of a wooden material having elasticity, it is possible to further prevent the hardware from coming out of the horizontal member by forming the hole slightly smaller than the outer diameter of the hardware. Therefore, it is possible to obtain a load-bearing wall structure that can maintain a secure tight state.
[0062]
[0063]
Furthermore , since the hardware is fixed by the adhesive, the hardware is difficult to come off from the horizontal member. In addition, since the outer diameter of the open end is smaller than the outer diameter of the other part, a gap is created between the hole and the outer diameter of the end, and excess adhesive is collected in this gap for bonding. It is possible to prevent the agent from entering the hardware from the end. Accordingly, it is possible to easily attach the hardware to the horizontal member.
